Jose Fernandez has torn UCL

LOS ANGELES -- Miami Marlins ace Jose Fernandez has a significant tear in his right elbow and the team doctor is recommending that he have Tommy John surgery.

A source told the Sun Sentinel newspaper that Fernandez will have the surgery by week's end in Los Angeles from orthopedist Dr. Neal ElAttrache.

However, Scott Boras, Fernandez's agent, said Wednesday night that his client has yet to commit to the surgery.

"I think he's got to walk through some steps before he makes a decision," Boras said.

Team president Michael Hill made the announcement in the Dodger Stadium press box during Tuesday night's game against Los Angeles.

"Pitching's a precious commodity and we've always tried to be very careful with it. So you try to err on the side of caution," Hill said. "We've done everything we've thought was the right thing, as to how we've handled him. It's just one of those things that happened."

The 21-year-old Fernandez was put on the 15-day disabled list Monday. Last season's NL Rookie of the Year was examined Tuesday by Marlins team physician Lee Kaplan in Florida.

"I think like any 21-year-old kid who hasn't had an injury or been hurt, it's tough," manager Mike Redmond said.

"I'm sure he feels like he's letting his teammates down because he got hurt, and all the things that come with the type of competitor he is. But all we really want is for him to be OK and getting himself healthy and getting back to the ballclub. That's the important thing," he said.

Fernandez is 4-2 with a 2.44 ERA in eight starts. He leads the majors with 70 strikeouts.

The Marlins said Fernandez is visiting with his family to talk about his options.

"He didn't really give us an idea of when," Hill said. "Obviously, a lot has gone on the past few days, so for him it's a lot to take in and a lot to absorb. So he's just taking the time to digest all the information he's been given from both doctors."

"From what the doctors saw, they did not want to go the rehab route. They felt like surgery was the best option, and that was the recommendation. Hopefully, we can make that call and get things set up and get it taken care of so we can get him on the road to rehab," he said.

The rehabilitation period for Tommy John surgery can be 12 to 18 months.

A bevy of pitchers has been diagnosed with torn elbow ligaments requiring Tommy John surgery since the start of spring training. They include Braves right-handers Kris Medlen, Brandon Beachy and Cory Gearrin; Diamondbacks ace Patrick Corbin; Athletics starters Jarrod Parker and A.J. Griffin; Rays All-Star Matt Moore; Yankees starter Ivan Nova; Padres starter Josh Johnson; Mets closer Bobby Parnell; Royals setup man Luke Hochevar; Tigers reliever Bruce Rondon; Astros reliever Jose Cisnero and top Pirates prospect Jameson Taillon.

Matt Harvey and Stephen Strasburg are other All-Stars who have had the ligament-transplant operation, which can take 12 to 18 months for recovery.

Fernandez's fastball averaged 94.6 mph over his first four innings in his most recent outing against the Padres but only 90.7 mph over his last two, according to ESPN's Stats & Information. He allowed four runs in the sixth inning before being removed with nobody out.

Last season Fernandez made 28 starts, going 12-6 with a major league-best .182 opponents' batting average. His 2.19 ERA was second in the majors behind three-time defending ERA champ Clayton Kershaw.

Right-hander Anthony DeSclafani was promoted from the minors and started Wednesday night in his major league debut as the Marlins beat the Dodgers 13-3.

The 24-year-old former University of Florida star was 3-4 with a 4.19 ERA in eight starts at Double-A Jacksonville.

"Out of all of our younger guys, he's probably a little more polished because he's a college guy and he's got a few more innings under his belt, as far as experience," Redmond said. "There's no doubt that losing Jose is a big blow, but it's also an opportunity for guys to step up and show what they can do."
